Astronomical image manipulation in the transform domain
It is well known that images are usually stored and transmitted in the compressed form to save memory space and I/O bandwidth. Among many image compression schemes, transform coding is a widely used coding method. Traditionally, processing a compressed image requires decompression first. Following …

Natural Language Driven Image Edits using a Semantic Image Manipulation Language
… one such application - natural language based image editing. We propose a novel framework to go from free-form natural language commands to performing fine-grained image edits. Recent progress in the field of deep learning has motivated solving most tasks using end-to-end deep convolutional …

The progression of photographic image manipulation in communication: An argument against the "revolution" of technological change
The technology of photographic image manipulation has evolved faster than our ability to consider its implications. This thesis looks at the recent evolution of image manipulation, which some regard as a "revolution." The various stages of technological progression are examined using examples …

Perception of Color Quality for Natural Images Viewed, Edited, and Printed Within the Context of a Home Digital Color Imaging System
… potential to influence consumers' perceptions of image quality and their subsequent image manipulation activities. Depending on the inherent color bias and apparent contrast of the CRT, extensive image manipulation may occur, significantly altering the digital values of the image. Output generated …

Investigating the use of synthetic media and real-time virtual camera filters for supporting communication and creativity
… study was conducted to explore real-time self-image manipulation via real-time camera filters (21 participants) in video calls. It was observed that applying such filters may trigger various responses in people with regards to mood, embodiment, and creativity. This thesis extends research into …

Generalized Constrained Interpolation
<p>Interpolation is essential in digital image processing, especially magnification. Many different approaches to interpolation specific to magnification have been developed in an effort to overcome the shortcomings of bilinear and bicubic interpolation. One of these approaches, Constraint-Based …

New tools to enable children to manipulate images through computer programming
… proposes a programmable toolkit for building image filters to make the concepts of basic image processing accessible and engaging to children. The toolkit was developed in the context of Scratch, a media-centric programming environment intended for children. For this thesis, I redesigned the …

Effects of grid lattice geometry on digital image filtering
… distribution of discrete sample points from an image affect digital image manipulation. The geometries of the grid lattice and edge are described for digital images. Edge detecting digital filters are considered for segmenting an image. A comparison is developed between digital filters for two …

MARK TWAIN'S SPEAKING IN THE DARK YEARS (COMMUNICATION, RHETORIC, MOVEMENTS).
… life. It includes Twain's informal readings, his image manipulation and control, his rhetorical speaking, his methods of speech preparation, and his dictation of the autobiography. Twain's use of oral interpretation is examined demonstrating the influence of the Reading Tour of 1884-1885. He read …

Segment-based image matting using inpainting to resolve ambiguities
Image Matting and Compositing [6, 25] - the extraction of a foreground element from an image and overlaying it over a different background - are two important operations in digital image manipulation. The extraction of the foreground element and its composition over an existing background is …

Accurate and Robust Localization of Duplicated Region in Copy-Move Image Forgery
Many studies in image forgery detection have demonstrated the importance of reviewing different types of the forgeries and possible detection methods. Region duplication is an efficient operation to create image manipulation. In this type of tampering a region in an image is copied and moved onto a …
